XOM API for Processing XML with Java

[Regier Avery J <RegierAveryJ AT JohnDeere.com>]

This is a non-null namespace associated with the whole document, which is 
unprefixed at the start.  See the test document.

Document doc = new Builder().build(new StringReader("<hi 
xmlns='there://mr.space/alien'/>"));
XPathContext context = 
XPathContext.makeNamespaceContext(doc.getRootElement());
context.addNamespace("a", context.lookup(""));
Nodes query = doc.query("//*[not(self::a:human)]", context);

I am trying to achieve a single xpath statement that works regardless of the 
namespace used.  This should be achievable (IMHO).  Even if you think it 
shouldn't be done, it's the wrong fix, since looking up the default namespace 
in the context should work.

It looks as if a bug has been fixed. It should not be possible to bind a 
prefix to the "null namespace".
